Prph tear of medial mensc, current injury, r knee, sequela

This code signifies a current, peripheral tear of the medial meniscus in the right knee that is considered a sequela of a previous injury. A peripheral tear typically involves the outer, vascularized portion of the meniscus. The "sequela" designation indicates that the current tear is a long-term effect or complication stemming from an earlier, distinct injury event.

Use this code when documentation clearly indicates a new or newly identified peripheral medial meniscal tear in the right knee, and the physician explicitly links it as a consequence of an old injury. This is appropriate for patients presenting with symptoms directly attributable to this specific tear, even if the initial injury occurred months or years prior. It should be used when the current tear is not an acute, new traumatic event but rather a manifestation of prior damage.

• Ensure documentation explicitly states the tear is "peripheral" and "medial."
• Verify the laterality is "right knee."
• Confirm the physician's assessment that the current tear is a "sequela" of an old injury, not a new acute injury.
